My sister's friend has a problem, and is terribly underweight.
She still has flab.
Everyone does, we need it.
Not just that, but unless you have muscle there, you will always look flabby.
It's natural.

If you don't want it, eat properly, exercise to turn it into muscle.
You think you can't, but you're a lot stronger than you think you are if you've already come through this once before.
